SPECIFICATION forming part of Letters Patent No. 593,406, dated November 9, 1897.

' Application filed May 4, 1897. Serial No. 635,007. (No model.)

To all whom it may concern:

Be it known that I, JOSEPH H. TEMPLIN,a citizen of the United States, residing at Birdsborough, county of Berks, State of Pennsyl- Vania, have invented certain Improvements in IVire-Coil Machines, of which the following is a specification.

My invention relates particularly to that class of wire-coil machines in which the coiled wire is inserted into materialsuch, for instance, as beltingfor the purpose of connecting abutting edges thereof. In Patent No. 581,316, issued April 27, 1897, is shown a machine of this class to which the present improvements, as hereinafter described and illustrated, have been especially adapted, though such improvements are also applicable to machines varying therefrom in details of construction. These improvements relate to the clamping-jaws which are employed in connection with the coil-inserting rolls, and especially to the novel manner in which said jaws are applied and operated.

Figure 1 is a front elevation of a machine embodying my improvements. Fig. 2 is an end elevation of the same. Figs. 3, 4, and 5 are similar cross-sectional views showing different positions of the coil-inserting rolls and of the clamping and flattening jaws. Fig. 6 is a similar View to Fig. at, but showing the previously-inserted coil flattened down between the jaws; and Fig. 7 shows the face of the jaws, indicating two ways of roughening the same.

A represents the main frame of the machine, A the column, and A the base upon which it is supported, the latter in the construction shown being provided with wheels A to permit its convenient movement from place to place and with hooks or anchors A to fix the same in a desired position to the floor.

I3 is a movable frame hinged to the main frame A by means of suitableears, through which pass the ends of the pivotal roll C. Additional rolls D and D, mounted, respectively, in the main frame A and hinged frame B, are geared with the pivotal roll C, from which they are both rotated no matter to what position the hinged frame is swung, so that a coil of wire inserted between the rolls and having the latter closed down upon it will be rotated by the exterior pressure of the rolls to cause the end of the coil to pass successively through a series of punctures made in a piece of belting or similar material held in its path.

The construction and operation of the parts above mentioned are the same as are fully described in the prior patent referred to, and the succeeding operation required is also the san1e-namely, the flattening of the inserted coil by means of pressure brought thereupon by clamping-jaws, the latter also serving to firmly hold the belting or other material during the operation ofinserting the wire. In said prior patent, however, the movable clampingjaw is carried by or forms part of the hinged frame B, and is therefore operated simultaneously with and by the same lever mechanism that lowers or raises the roll D to rotate or release the coil. In my present construction the clamping movement is made entirely independently of the roll movement, thus permitting the more satisfactory operation of the machine, with greater variation in thickness of material.

In my improved construction, as shown in the drawings, the lower clamping-jaw a, in front of the rolls, is secured to or forms part of the fixed frame A of the machine, as before. The upper jaw F, however, forms a separate part and is independently pivoted to lugs a at the rear of the machine by means of integral hinge-arms E, which are carried over the roll-frame, and the lower ends of which are engaged by pivot-pins a located in about the same plane as the center of the pivotal roll 0, so that the face f of the jaws may be caused to rise and fall in a practically vertical line. This movement of the jaw F upon the pivot a is effected, as shown, by the following mechanism: The jaw is carried by a longitudinal shaft G, having eccentricallyformed ends mounted in the top ends of vertical links H, the lower ends of which latter are carried upon the projecting ends of a parallel shaft G in the main fralneA of the machine. These projecting ends of the shaft G are also preferably eccentric, and both shafts have clamping-levers secured thereto, (marked g and g, respectively.)

In operating my improved machine the belting or other material is first placed in proper position between the jaws, the upper one of which is then closed down upon it by operating one or both of the levers g g, as the case may be, the amount of movement imparted to the jaw and the pressure secured being in proportion to the eccentricity of the supporting ends of the shaft and the movement and power applied to the levers, which latter may be as much or as little as the case may require independently of any other consideration. The rolls are then operated independently to bear upon and insert the coil and thereafter release the same, following which latter operation the clamping-jaw Fis raised, the belting moved outward to bring the inserted coil between the jaws, and the latter closed to flatten the coils, the additional power provided by the two-lever arrangement described being especially valuable in this operation, which requires great force to properly effect it. In closing the jaws upon the coil to flatten the latter I have found that the convolutions in contact with the faces of the jaws tend to slip in an axial direction upon the latter, thus producing an unsatisfactory result.

transverse grooves formed in the faces of the jaws to receive each convolution of the coil, which grooves are adapted to change the angle of the convolutions; but such grooves must be spread to suit the pitch of a particular coil, and even when so spaced it is practically troublesome to insure the engagement of each convolution by its proper groove, owing to a lack of perfect uniformity in the pitch of the coil, so that the use of such grooves merely to prevent axial slippage of the convolutions when subjected to the flattening pressure is unsatisfactory. I have found that such slippage of the convolutions without regard to the'pitch of the coil is effectively prevented by finely roughening the surface of the jaws, without forming transverse grooves adapted to positively engage the wire, such ro-ughenin g being similar to the face of a finecut file, or otherwise roughened, as indicated in Fig. 7, and merely serving to hold the rounds of the coil in contact with the particular point of the jaw which first touches it in closing upon the coil toflatten it.

This improvement I find to be of great practical value, inasmuch as it insures the flattening of the coil without bending the convolutions lengthwise of the coil.

What I claim is- 1. A wire-coil machine having a series of rolls arranged to close upon and rotate an in- I terposed wire coil, clamping-jaws operating in connection therewith, and separate mechanisms for independently opening and closing said rolls and jaws, substantially as set forth.

In the prior patent referred to this is prevented by the 2. In a wire-coil machine having a series of rolls arranged to close upon and rotate an interposed wire coil, clamping-jaws operating in connection therewith, and two levers each adapted to partially open or close said jaws and jointly to completely open or close the same, substantially as set forth.

3. In a wire-coil machine having a series of rolls arranged to close upon and rotate an interposed wire coil, clamping-jaws in front of said rolls having a movable member pivoted at the rear thereof, and mechanism for operating said movable member, substantially as set forth.

4. In a wire-coil machine having a series of rolls arranged to close upon and rotate an in-' terposed wire coil, clamping-jaws in front of said rolls having a movable member pivoted at the rear thereof, and a mechanism for operating said member and mounted on links pivoted to the frame of the machine, substantially as set forth.

5. In a wire-coil machine having a series of rolls arranged to close upon and rotate an interposed wire coil, clamping-jaws in front of said rolls having a movable member pivoted at the rear thereof, a mechanism for operating said member mounted on links pivoted to the frame of the machine, and mechanism for operating said links to further move the jaws, substantially as set forth.

6. Ina wire-coil machine having a series of rolls arranged to close upon and rotate an interposed wire coil, clamping-jaws in front of said rolls having a movable member, and a mechanism for operating said member mounted on links pivoted to the frame of the machine, substantially as set forth.

7. In a wire-coil machine having a series of rolls arranged to close upon and rotate an interposed wire coil, clamping-jaws in front of said rolls having a movable member, a mechanism for operating said member mounted on links pivoted to the frame of the machine,

and a mechanism for operating said links to further move the jaws, substantially as set forth.

8. In a wire-coil machine having a series of rolls arranged to close upon and rotate an interposed wire coil, clamping-jaws in front of said rolls having a movable member pivoted at the rear thereof, an eccentric shaft for operating said member, and links carrying said shaft and riding upon a second eccentric shaft mounted in the frame of the machine, substantially as set forth.

In testimony whereof I affix my signature in presence of two witnesses.
